Sony made it clear when it first unveiled the PlayStation 4 earlier this year that the new console will not be backwards compatible, meaning that gamers would not be able to pop in PS3 game discs into the console to play those titles. However, PS4 owners will be able to play PS3 games thanks to Sony’s Gaikai streaming service, which would allow gamers to stream PS3 titles from the cloud. Sony’s recent announcement about PS4 global sales also reveals that the GaiKai PS4 streaming service will work with the PlayStation 3 and PlayStation Vita as well.
The way this service would work is that gamers will have to pay a subscription fee to have access to “a catalogue of critically acclaimed PS3 games on PlayStation 4 and PS3, followed by PlayStation Vita.” The service would let them play those titles by simply streaming them from remote service, gamers won’t have to locally install those titles. So despite the fact that PS3 discs are not compatible with PS Vita and PS4, gamers will still be able to play those titles after paying a monthly subscription fee. Sony hasn’t provided an exact timeframe during which we can expect the service to go live, it has only said that Gaikai will be available in the U.S. next year, gamers in the UK might have to wait until 2015.
